Tumor in the plantar region : dermatofibrosarcoma protuberans in an infrequent topography

Abstract

Dermatofibrosarcoma protuberans is a rare mesenchymal tumor; it is locally aggres-sive and presents high rates of local recurrence. It may present as a nodular or plaque vegetatinglesion. It mainly affects the trunk and proximal limbs, being rare in the distal extremities. Biopsy and immunohistochemistry help confirm the diagnosis. The authors report a case of der-matofibrosarcoma protuberans with plantar region involvement, a rare presentation. To thebest of the authors’ knowledge, only 11 cases of involvement of the feet were described in theinternational literature.
